LIGHTING GAS-LAMPS.

SPECIFICATION forming part of Letters Patent No. 509,531, dated November28, 1893.

Application filed June 8. 1893. $erial No. 476,968. (No model.)

To all whom it may concern.-

Be it known that I, IGNATZ HARTIG, a sub ject of the German Emperor, anda resident of Munich, Bavaria, Germany, have invented certain new anduseful Improvements in Lighting Gas-Lamps, of which the following is aspecification.

The purpose of the present invention is to provide means by which aseries of gas lamps such as the lamps of a railway train may be lightedwhen desired, and also extinguished, all by one movement for the one orother purpose, and without the necessity of entering any carriage orcompartment or of mounting upon the roof of any carriage, the same beingmoreover equally applicable for action whether the train is in movementor at a standstill.

This invention depends principally upon the employment of anunstretchable chain passing along the roofs of the carriages of thetrain and connected at intervals to lever mechanism so that by pullingon this chain the various mechanisms are operated and cause the gas tobe turned on in each lamp and small continuously burning pilot flames tobe brought into position to light the main flames and to afterwardresume their places. The chain, maintained against the action of acounterspring, when released will be drawn back by the said spring andwill extinguish the main flames of the lamps by cutting oit the gassupply thereto. 7

In the annexed drawings Figure 1 is a plan view of the mechanismattached to one of the lamps. Fig. 2 is a similar view of the same partsin the position occupied when the main lamp is lighted. Fig. 3 is across section on line 3, 3, Fig. 1, and Fig. 4 a cross section on line4, 4 Fig. 2. Figs. 5 and 6 are elevations of the mechanism connectedwith the pilot flame and gas supply cocks on a larger scale.

In each lamp is themain gas burner asupplied through pipe at from thegas cook h to which the pipe 1) leads from the gas supply main 0. On thespigot of the cock h is the pulley 11 around the grooved periphery ofwhich a chain 70 passes. The one end of this chain It is connected to aspring 13 supported by a pillar or otherwise fixed immovably inposition; the other end of the chain passes to a lever 'n' (Fig. 1) tothe end of which it is connected. On the side of the pulley 1 is a fixedprojecting finger land in the path of this finger Z is a tongue m uponthe pilot burner d. The pilot burner d rocks upon the spigot end of agas supply pipe e so that this connection forms a gas cook 9 for controlof the supply of gas to the pilot flame. The main f supplies the pipese. The pilot burner d carries a weight d which tends always to keep thesaid burner in a vertical position as shown in full lines in Fig. 5 orto return it to this position after it has been tilted as shown indotted lines in this figure. The tongue m is supported by the spring711. which sufiers the tongue to give way to the return of the finger I.

It will be obvious that if any pull is given to the chain in thedirection of the arrows in Fig. 5, the pulley '5 will be revolved. Thefirst result of this movement is to commence to gradually open the gascook h and supply gas to the main burner a. The finger Z in its movementmeets the tongue m and lifts the latter thus tilting the pilot burner 01into a horizontal position as shown in dotted lines (Fig. 5) wherebyalso the gas supply to this burner, previously at a minimum, isgradually increased as the burner 01 is directed downward within thechimney 0 above the burner a. The gas issuing from the main burnera isthus lighted and will continue to burn so long as the supply continues,that is to say, so long asthe pull is continued on the chain k. Thefinger Z having attained the position shown in dotted lines in Fig. 5moves out of the path of the tongue m whichthus is enabled to return toits previous position together with the pilot burner 61 under influenceof weight 01'. When the pull on the chain 7c is released the spring 19returns the chain to its first place, the pulleyt' revolves in thecontrary direction and the cook it is closed thus extinguishing the mainburner a. The spring m permits the tongue m to give way for returnpassage of the fingerl as previously mentioned.

As in the coupling up of carriages to form a train sometimes the oneend, sometimes the other end of a carriage will come first, it isimportant to be able to operate this mechanism equally by a pull fromeither end of the carriage so that when all are coupled together thepull may be in one direction only. For this purpose the following devicemay be used: The lever it before referred to, to which the chain is isattached at one end, is pivoted at the other end at q to a suitable baseor frame such as q. On this frame is pivoted centrally at r a lever 12which has a perpendicular arm n to the end of which the chain 3, whichpasses along the roofs of all the carriages, is attached. The lever nlies within a triangular yoke n, the apex of which is connected to thelever n, and the lever n engages with one endin one of the angles at thebase of this yoke and with the otherend in the other angle at the baseof the yoke. Thus whichever way the lever arm n is drawn laterally fromits mean position, one of the arms of the lever n draws outward theyoken (see Fig. 3) and with it the lever n and chain 70.

For the coupling up of these mechanisms there are provided suitablelengths of chain 8 and at each end of each carriage a spring 25.Nevertheless only the free end of the coupled upchains s which is overthe end of the last carriage is attached to the spring 25 found there,the other springs being left idle. The chain 8 suitably coupled up leadsfrom the last carriage to the other end of the train, to the locomotiveor to the guards brake van or otherwise where it may be attached toalever with a retaining ratchet or any other device by which it may bepulled and held from returning to its previous position until released.

I claim as my invention- 1. The combination withachainsof a chain is, amechanism for transferring the pull of said chain 5 in either directionto chain k, a

gas cock controlled by chain 10 and adapted to supply gas to the mainburner of a lamp, and a pilot burner adapted to be moved, by action ofsaid chain 70, temporarily into the chimney of said lamp for lightingthe same.

2. The combination with the main burner of a gas cook thereto, a pulleywheel on the plug of said gas cock, a chain passing over said pulleywheel, a rotary mounted pilot burner and a finger on said pulley wheeladapted to revolve said burner substantially as and for the purpose setforth.

3. The combination with a chain In adapted to turn on a gas cook andmove a pilot burner for the purpose described, of a lever n,a yoke nconnected thereto, a balance lever 12. adapted to draw said yoke whenrocked in either direction, an arm n to said lever 01 and a chain .5substantially as described.

4. In a train of railroad carriages the combination in each gas lamp ofa main burner, a gas cook thereto, a movable pilot burner, a chain 70adapted to control the main gas cock and the said pilot burner, a chains connected to operate all the chains k, aspringtadapted to tension thechain 3 and mechanism for pulling and holding the chain 8 againsttension of the spring t substantially as and for the purpose set forth.

In witness whereof I have signed this specification in presence of twowitnesses.
